REMOVABLE CALK FOR HORSESHOES.

Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed March 26, 1908. Serial No. 423,443.

T 0 all whom it may concern:

Be it known that I, ISAAC S. BRASSINGTON, a citizen of the UnitedStates, residing at Mount Carmel, in the county of Northumberland andState of Pennsylvania, have invented certain new and useful Improvementsin Removable Calks for Horseshoes; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon, which form a partof this specification.

This invention relates to new and useful improvements in removable calksfor horseshoes and the object in view is to produce a simple andefficient device of this nature so arranged that the calks, when wornout, may be easily and quickly replaced by new ones, the calk having ashank portion held in place by means of a tapering dove-tailed keydesigned to engage a notch in the end of the shank which is at rightangles to the calk,

while the opposite end of the calk has dove- I tail connection with theshoe.

The invention comprises various details of construction, combinationsand arrangements of parts which will be hereinafter fully described andthen specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a perspective view showing the shoe with the calk fastenedthereto. Fig. 2 is a cross sectional view on line 22 of Fig.

1, and Fig. 3 is an enlarged detail view of the locking key.

Reference now being had to the details of the drawings by letter, Adesignates a horseshoe having a rectangular outlined slot B formed inthe toe thereof, one end wall of said slot being preferably inclined, asat C. A dove-tailed slot D is formed in the under surface of the shoeand cuts transversely through said slot B.

E designates a toe calk having a shank portion E, one end F of which isat an acute angle to the length of the calk forming, with the 'nclinedend C of the slot B, a dove-tail connection. The opposite end G of theshank of said calk is at right angles to the calk and has a transversegroove H formed therein, which groove, when the calk is adjusted withsaid shank in the'slot B, registers with the grooved slot D.

K designates a key which is dove-tailed and tapering and is designed toengage the dove-tailed slot D formed in the toe of the shoe and also toengage the groove or notch H formed in the end of the shank E, therebysecurely holding the calk in place. Suitable heel calks J are providedwhich are each held in place by means of a tapering dove-tail key Kengaging the shank of the calk in the same manner as described in thetoe calk.

From the foregoing, it will be noted that, by the provision of ahorse-shoe having a removable calk made as shown and described, a simpleand efficient means is afforded whereby the calk may be securely held inplace and easily removed when desired to replace the same by a new calkor for other pur poses by simply loosening the wedge-shaped dove-tailedkey.

What I claim to be new is 2- A removable calk for horse-shoescomprising, in combination with a shoe having an elongated slot formedin the toe thereof, one end wall of said slot being inclined, the otherend at right angles to the face of the shoeand provided with a taperingkeyway at the lower marginal edge of the opening, a toe calk having ashank portion conforming to the shape of the slot at the toe of the shoein which it is seated, one end of the shank of said calk being undercutand forming with the inclined end wall of the slot a dove-tailconnection, the opposite end of the shank of the calk having a taperingkeyway opposite the keyway in the end of the slot, a tapering key havingits opposite longitudinal edges inclined to conform to said inclinedkeyways and adapted to hold one end of the shank of the calk indove-tail connection with the end of the slot, a space interveningbetween the opposite end of the slot and the adjacent end of the shankof the calk, as set forth.

In testimony whereof I hereunto alfiX my signature in the presence oftwo witnesses.

ISAAC S. BRASSINGTON.
